President Obama’s Cabinet The president appoints 16 members to his Cabinet, in addition to many other high-profile positions. Some members of President Obama’s first-term Cabinet announced their departure after the first term ended, and the president has nominated replacements for many of them.

Secretary of State Hillary Rodham Clinton was hospitalized in New York on Sunday after doctors monitoring her recovery from a concussion discovered a blood clot, according to a statement from her office.

The statement said that “in the course of a follow-up exam, Secretary Clinton’s doctors discovered a blood clot had formed, stemming from the concussion she sustained several weeks ago. She is being treated with anti-coagulants and is at New York-Presbyterian Hospital so that they can monitor the medication over the next 48 hours.

“Her doctors will continue to assess her condition, including other issues associated with her concussion. They will determine if any further action is required.”

Clinton aide Philippe Reines, who issued the statement, declined to provide further details.

Reines said on Thursday that Clinton’s recuperation was continuing and that she was expected to resume her office schedule this week.

Clinton, 65, has not been seen in public since the first week in December, when she reportedly contracted a stomach virus during a trip to Europe. On Dec. 15, the State Department said that she had fainted at her home two days earlier, as a result of dehydration from the virus, and had sustained a concussion. The State Department said that her doctors had advised further rest.

During her absence, Clinton canceled an overseas trip and her scheduled testimony before Congress about the Sept. 11 attack on a U.S. diplomatic compound in Benghazi, Libya. She also did not appear at the White House on Dec. 21, when President Obama introduced Sen. John F. Kerry (D-Mass.) as his nominee to succeed Clinton.

Republicans have said that they are likely to hold up Kerry’s nomination hearing until Clinton testifies about the Benghazi attack, but the impact of this new disclosure was unclear.

Clinton said two summers ago that she would not stay in her job in a second Obama term.

Before the announcement about Clinton’s hospitalization, Obama appeared Sunday on NBC’s “Meet the Press” and reaffirmed an earlier decision by Clinton to carry out all 29 recommendations made by a State Department review panel that examined the circumstances surrounding the attacks in Benghazi that killed U.S. Ambassador J. Christopher Stevens and three other Americans on Sept. 11. “My message to the State Department has been very simple, and that is we’re going to solve this,” he said. “We’re not going to be defensive about it; we’re not going to pretend that this was not a problem — this was a huge problem.”

Obama said one major finding — that the State Department relied too heavily on untested local Libyan militias to safeguard the compound in Benghazi — reflected “internal reviews” by the government. “It confirms what we had already seen based on some of our internal reviews; there was just some sloppiness, not intentional, in terms of how we secure embassies in areas where you essentially don’t have governments that have a lot of capacity to protect those embassies,” he said.
